Thanks @KathrynG3 ,
As I stated, I did not see a form 2210 in my 2019 TY form 1040. Only in the Federal carryovers worksheet do I see a line 6 that says tax liability for form 2210 or 2210 F . I do use a Mac OS Mojave.
So it sounds safe to assume that since most of my income last year due to Unemployment Insurance (UI) (electively taxable, and I only elected about half the time). So the 10% withheld on Fed tax from UI was no where near what I regularly make and therefore did not reach the 90% threshold??
As I tried to finish the TT for 2020 the software told me the 2210 form will not be available until 2/11/21, so I can't complete it anyhow just yet it seems.
