If I am doing an individuals business schedule C, do I list off ALL of the expenses that add up to the $5,000 federal start up cost or do I just put $5,000 in that box and anything over that amount gets itemized?

Any input is greatly appreciated about how this functionality works.

I don't know the answer (I use ProSeries, not Proconnect Online), but have you tried typing in a large number and checking what shows up on Schedule C?

For example, if you enter $10,000, does Schedule C show $10,000 or does it show $5000 plus some amortization?

Thanks for this. I can see how to input it now.

You should run it  through the depreciation area, under amortization under code section 195 which says start up costs or just use the override on the schedule C input that you showed in your question.
