Turbo tax premier and big mistakes

[lizC]

This is my first time using turbo tax, I always have done my own taxes using the irs forms and instructions and state.  After doing my sons simple taxes, the turbo tax program has made some major mistakes and I don't understand how it did this.  It has completed an alternative minimum tax form for him and then on the 1040 it has listed the tax which was withheld from his pay on the overpayment line and nothing on the refund line.  He is due a large refund.  Please help me understand why this program has made such huge mistakes on very simple taxes which were just supposed to be the 1040 and one line on schedule 1.  very simple taxes.

So, there is a number on line 20, but nothing on line 21a?

Is there a figure on line 22?

Line 20 has a number on it but it doesn't belong on that line and line 21a and line 22 has nothing on them

Since it is a simple return, the best course of action would be to Clear & Start Over. 

1. Log in and continue your return.
2. Select Tax Tools near the bottom of the left side menu.
3. Select Clear & Start Over.
4. Confirm that you want to clear your return. 

This will remove all of the information that you have entered this year.
