Retirement tax questions

I had owned my employers stock in my 401k account in 2020.   But then I left that job and sole that stock in 2020and moved the proceeds into an IRA account.  Do I have to report those stock sales on my federal tax return even though I owned that stock in a retirement account and, after I sole the stock when I left the company, I moved the proceeds from that 401k account of my former employer to another retirement account (IRA)?  If so, where do I report this on the tax return - is it reported with regular non- retirement stock sales?

thanks
