You can go ahead and prepare your 2021 return on the assumption that your amended 2020 return will be processed as it was filed.
Then, if you are expecting a refund from your 2020 amended return, you can wait until the last minute to actually file your 2021 return to see if you get your 2020 amended refund. If you do not, then you can decide which steps to take with regard to your 2021 return. The IRS is working through a tremendous backlog, so your amended return may not be processed before the due date of your 2021 return.
If you expect a refund from your 2021 return, then filing an extension would pose no issues. But, if you have a balance due for 2021, you will still be expected to pay the tax by the due date.
So, even if you do need to amend your 2021 return later after getting word from the IRS about your 2020 amended return, filing it on time may still be your best option.
