I think I had a similar issue moments ago. I had purchased the Deluxe download. and when I was ready to file Turbotax was asking me how I wanted to pay for it? I just forked over $80.00 (but should have bought through Costco! $49. for the same thing. but back to the issue, It went into a tail spin and wouldn't go any further. I simply exited fully out of the software and re-entered opening my current tax return and it finally went through.
With what your experiencing I would get to the point where it is crashing and choose to support button to get help filing. I had an issue last year like this and they were able to walk me through it. I know it is cutting it late but give them a call before pulling your hair out and, get them to walk you through it...
Hope this helps!
