Ironically, my first thought when the original error occurred was to do what you suggested and just remove the tax money from the ROTH and submit the tax payment myself. I didn't do that because two transactions were recorded in both the Traditional IRA and the Roth, one for the the net after tax amount, and one for the state tax amount. The transaction for the state tax amount had a description of state taxes withheld in both places.
I was concerned that the state tax withheld amount would be incorrect on the 1099R and I thought correcting the error at the source would be better. I'm going to have to rethink this whole process for this year. Thank you for your help. I appreciate your assistance.
