My returns got rejected because I forgot to enter a First Time Homebuyers repayment plan from 2008. How do I fix it?

When I go back to the repayment page, I click that we did receive the payment on 2008, but sold the home and no longer live there...it should just delete it, but  It's like there's a glitch in the system and it won't update to what I clicked so I'm stuck with the same problem.
