Unfortunately, while your local copy of Turbotax knows there is an error, you won't be able to fix the problem until the return is rejected by the IRS and sent back for correction.
I think it is possible that you could prepare and file a new return (if we assume that form 5695 is now fixed). If using Turbotax installed on your own computer, this is free. The second might go through and when the first is rejected, you ignore it. However, if using Turbotax online, you would probably have to pay a second time, and I don't know if you can get a refund.
