what button.  when i click the magnifying glass, i'm just taken to the worksheet, not the line that needs completed.

what version of ProSeries are you using?  You don't have a similar screen as I posted below?

yes, i have a similar screen and i have an 8829 worksheet.  what line on that worksheet needs to be populated?

In the 8829, mark YES at the top to select the simplified method, then scroll down to Lines 1 and 2 to enter the square footage amounts...that should pull/push the information over to the Sch C line 30a
