Unreceived 2019 refund: enter as payment on 2020 return?
For 2019, I filed for an extension in July 2020 (paper), then filed the 1040 in Oct. 2020 (paper). I was owed a large (>$8k) refund, and specified direct deposit (acct. info is correct). Refund has not been received. I was sent a letter from IRS in March 2021 saying they needed more time to "process your claim." Can I just record the amount as a payment on my 2020 return, even though I requested the refund? Is there another form I should file first?
