In 2020 I took 401K early withdrawal due to Covid disaster. I took $100,000 out and had $10,000 taxes withheld.  When I divided repayment over 3 year it came to $33,333 per year.  Where was the $10,000 supposed to be entered in 2020 taxes?  I am trying to do my 2021 taxes and want to make sure that I got credit for it.  Thank you
