Well, I went ahead and performed the work around by manually entering the $600 on Line 12B in both the entry window and in the form shown in the error reporting window that appears when TurboTax Deluxe runs the final returns analysis. After making the correction, I made sure to avoid running another returns analysis. When I came to the step to e-file my Federal return, I printed a copy before e-filing and and was able to confirm that the Line 12B amount showed $600. I then went ahead and e-filed my Federal tax return, which was accepted by the IRS 30 minutes later. So the workaround does work. But it is a shame that this software bug has not been corrected by Intuit in a TurboTax update.
