I put the fed income tax withheld  on the same screen that I entered the Social Security $ amount made in 2020. 

Get a critical - Fed income tax withheld entries present for tax payer in the withheld section of the misc. Income screen must be moved to the "From 1099-MISC NEC for efile tax returns" section of misc. income for efile purposes.

I'm not finding the screen to put the Fed income tax withheld from SS to make the critical diagnostic go away.
