After you file

An excess contribution to an IRA converted to Roth IRA becomes an excess contribution to a Roth IRA.

In the year of conversion, you would file Form 5329 Part III and  Part IV, and in later years Form 5329 Part IV.

 

An after-return-due-date excess contribution is resolved by having the custodian give you a straight distribution of $1000 from your Roth IRA.

Therefore, wait until Oct 16, 2025 to take out the $1,000.

You will pay one year's penalty on an amended 2024 tax return.
