Can I get an extension on the TurboTax early-filing discount?

TurboTax has offered me a price discount if I file by Feb 28. But there is a TT bug in computing foreign tax credit that is not scheduled to be fixed before March 3. See this thread:

In my case, I have no foreign tax credit, but TT insists on claiming a $61 credit, and there appears to no way for me to set it to zero. Thus, I cannot file a correct return until after the Feb 28 deadline for the price discount.

Can this deadline be extended?
