Business & farm

In Turbo Tax Business  (2019), When I entered the estimated quarterly Tax paid in S Corp Information Worksheet , Part III , For some reason on Form 1120 S Section 26 " Overpayment " TT business automatically refund entire amount you entered in S Corp Information Worksheet , Part III. Why is it happening?

 

As a work around, I am leaving S Corp Information Worksheet , Part III as zero.

 

Any guidance will be much appreciated.
