When did you move out of the house where you received the 2008 credit?
The IRS first time homebuyer database apparently says you still owe repayment. If you moved out of the house in a prior year, you were required to file form 5405 as part of that year’s tax return. In most cases, you were required to repay the full remaining amount of the credit at that time, and no repayment afterwards is owed.
If you did file form 5405 with your tax return in the year you moved out of the house, then you need to contact the taxpayer Advocate office service to get them to fix your their database.
If you did not file form 5405 in the year you moved out of the house, you can’t make a payment this year, and you will have to file by mail because of the rejection. You also need to go back and file an amended tax return for the year that you moved out and report the sale on form 5405 and repay the remaining amount of the credit. (if you sold at a loss, you will not have to repay the remaining credit, but I suspect this is unlikely 13 years down the road.)
