Get your taxes done using TurboTax

Thanks, this helps.  I am paying $4000 for the estimated liability of approx $1500 to avoid any penalties.  My questions are:

1. Does TT share the 4968 line #4 data with IRS?

2. I am seeing "Make your estimate as accurate as you can with the
information you have. If we later find that the estimate
wasn’t reasonable, the extension will be null and void." in the instructions. 

Will my overpaying considered as unreasonable?
