We are using a P.O. Box on the 1040, still leave the Schedule C blank? Thanks for your help.Business was conducted at a different address altogether. My husband...

The Schedule C instructions specifically say to not use a P.O. Box, so I don't understand why you say I can put it in. Maybe I am being dense!

So, should I leave the address blank on the Schedule C if I have a P.O. Box on my 1040?
