How to change the chapter format?

Question

I would like the name Chapter [No.] on top, below the actual \chapter.

<- I want it like this.

<- but it looks currently like this.

I would like the format of 1 but not its size of the fonts; the font like in 2.

\documentclass[egregdoesnotlikesansseriftitles,headings=optiontoheadandtoc]{scrreprt}
\usepackage{newtxtext}
\setkomafont{chapter}{\rmfamily \LARGE}
\addtokomafont{subsection}{\normalfont \itshape }

%code below here does not seem to work
\renewcommand*{\raggedchapter}{\centering} %chapter in toc and on page (numbering)
\renewcommand*{\chaptermarkformat}{\chapappifchapterprefix{\nobreakspace}\thechapter\autodot:\enskip}
\let\originaladdchaptertocentry\addchaptertocentry
\renewcommand*{\addchaptertocentry}[2]{%
  \IfArgIsEmpty{#1}
    {\originaladdchaptertocentry{#1}{#2}}
    {\originaladdchaptertocentry{\chapappifchapterprefix{\nobreakspace}#1\autodot}{#2}}%
}
\RedeclareSectionCommand[
  tocentrynumberformat={\def\autodot{:}},
  tocdynnumwidth
]{chapter}

\let\originalappendix\appendix
\renewcommand*{\appendix}{%
  \originalappendix
  %\renewcommand*\chapterformat{}% remove the chapter number  from chapter heading
  %\renewcommand*\chaptermarkformat{}% remove the chapter number from header entry
  \renewcommand*{\addchaptertocentry}[2]{% remove the chapter number from ToC entry
    \originaladdchaptertocentry{}{##2}%
  }%
}

Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. — Alessandro Cuttin, Feb 29 '20 at 21:51
It seems you've slightly misunderstood the function of egregdoesnotlikesansseriftitles. It changes all section headings to the rmdefault font, you don't need to add \rmfamily to addtokomafont or setkomafont commands for headings. — TivV, Feb 29 '20 at 21:53
@TivV okay I think I understand now; I am sorry I am not good with LateX — Karl L., Feb 29 '20 at 21:58
See my answer to your previous question: How to create a Chapter 1: TITLE in table of contents and header in the document? — esdd, Mar 01 '20 at 12:25

The KOMA-Script option for this is called chapterprefix (it can be found in the KOMA Script Manual in section "3.16. Document Structure").

\documentclass[
    egregdoesnotlikesansseriftitles,
    headings=optiontoheadandtoc,
    chapterprefix=true
    ]{scrreprt}

\usepackage{newtxtext}
\addtokomafont{chapter}{\LARGE}
\addtokomafont{subsection}{\normalfont \itshape}

\begin{document}
\chapter{First Chapter}
\end{document}
