I thought I saw someone else mention this, but then they discovered they marked the Do Not Calculate Estimates box.

Its rare I have anyone with a 1041 that needs to pay estimates, so I havent noticed....make sure its not a PEBKAC error (Problem Exists Between Keyboard And Chair) and be sure no wrong boxes are checked.

I just checked a dummy return, threw 100k of income on it and the vouchers filled in...you cant tell by looking at the 1041-ES Wkst though, you have to look at the actual 1041-ES in the forms in use list.

I too tried a dummy return and it worked so the problem is just in the one clients file.  Override is your friend.

thanks for the help.

Most of my returns are dummy returns. That is why they come to me.
