Amending return for IRS $15 interest 1099 and now shows $441 refund for Premium Tax Credit- but received check in the mail already!

I needed to amend my return to add a1099 IRS interest form I received for $15 dollars after I already filed.  I ran the Amend form process and it now shows I am due a refund of $441. After some extensive research, determined it was the Excess Premium Tax Credit (due back due to the American Rescue Plan as of April 9th, 2021).   The problem is, I just got a check in the mail for $441 dollars and I still need to file the amended return for the $15 (1099 INT from the IRS).  My state now also says I owe $10 I'm assuming due to the PTC of $441.  What do I do?  I can't file an amended return for $441 refund when they already sent checks out to refund the tax payers?  There should be a question on the form to ask if you have already received the refund, just like the stimulus checks so it adjusts off the amount it is adding back in.
