Retirement tax questions

@AmyC I will check out the references you gave; and if I need no further help; I will make this as the best answer.
I was wondering when we will know AGI Taxable levels for 2021?  Is that known now?   We have only 2-3 weeks to make our decision.  Is there someone at Turbo Tax that will help with planning; I presume for a fee of course?

I am presuming that I could buy in at, up to,  maximum for married couple into one type or another IRA @ I believe $14,000 ($7K + $7K) Married, to reduce tax bracket, if my calculations are not too far off for that year, provided I do it in a timely manner before end of 2021.    Near as I can figure, we definitely want to avoid going from 12% to 22% tax bracket.
