If you moved out in 2021, you were supposed to report that fact on your 2021 return, using form 5405. That would calculate your gain or loss on the sale, and if you have a gain, then you immediately repay all remaining credit balance. After that, you make no further repayment, so you did not owe a $500 repayment in 2022 and you don't owe one in 2023.
Either you did not report the sale correctly, or the IRS did not record it correctly.
For 2023, you should file by mail without making a $500 payment.
Then, go back and look at your 2021 return. If you did include form 5405 reporting the sale, contact the taxpayer advocate to get your records corrected.

If you did not include form 5405 to report the sale, you need to file an amended 2021 return that shows the sale and calculates any repayment.
Unfortunately, even if you report the sale of your home as a capital gain on schedule D, that does not automatically trigger form 5405, you have to go into the FTHB section and run that interview separately.
