What was the date on the checks?
Did you get a 2020 1099-R for the QCD distribution?
What date does your year end IRA account statement say the funds came out of your account?
Q. Do I recognize these QCDs on my 2020 or 2021 tax returns?
Simple answer: whatever year the 1099-R was issued for.
But you may have a bigger question: did you meet your 2020 RMD requirement (not applicable if you were under 72, and over 70.5)?
"For a QCD to count towards your current year's RMD, the funds must come out of your IRA by your RMD deadline, generally December 31." Reference: https://www.fidelity.com/building-savings/learn-about-iras/required-minimum-distributions/qcds
