Estimated Tax Payment Form doesn't work

The Estimated Tax Payment Form doesn't work.  It defaults to 100% (110%) of your 20-24 Taxes... in the top box with the 4 choices.  Selecting any of the other three choices erases the voucher values and takes you to another unrelated form.  None of the number entires are editable.  Selecting one of the first three boxes results in the corresponding value being blank and not editable.  There is currently no way to adjust the amounts in the vouchers.  The default is too high.  

 

In the second section, it shows a Taxes due after withholding (third line) value that is too high with no indication where it is coming from and no way to adjust it.

 

I've wasted a few hours now trying to get this to work and made three calls to the support line only to get cut off each time (average wait time 30 minutes each).  I did get through once to a person that then transferred me to another and then got cut off part way through describing the problem to the second person.

 

I've been using this product for many years and have always had some bugginess to it, but this year by far is the worst.  First the tax summary page wouldn't print (was missing) from the printouts and now this.  At least the State version of this form works, but meanwhile I'm stuck with incorrect Federal vouchers.

 

This is crazy!
