Ahh ok, I just did 2021's 8606 form exercise and line 14 came out to be ~$5500. Then let me know if this is correct...

You said I should "Once that's done, redo your entire tax return because you had taxable conversion that you didn't include, which changes Form 1040 line 4b and everything downstream. Compare the old and the new tax returns and fill out Form 1040X.
Mail the signed Form 1040X and 2021 Form 8606."

Can I do the above and then also submit my 2022 taxes in parallel given that now I know that my 2021 basis was $5500 and that unblocks me from finishing up my 2022 taxes?

Also just curious do you think I'm in for a sizable IRS penalty based on the error? Should I write a note to them and say it was an accident and hope they will be lenient? My first time ever having this happen...

Thanks so much, appreciate all this

Yes.

No idea. Pay the tax you can calculate and wait for the late bill.
