Federal return was accepted. MS rejected with code XMS00-091. The Error Detail says, "If Taxpayer Business Income/Loss is entered, then Schedule C or C-EZ must be included."

So, ProSeries doesn't know this and simply attach necessary forms to e-files? Is there a box I should check to get this to happen? Or am I missing something else?

Surely MS doesn't want a paper return from every taxpayer that files a Sch. C!

I'm bamboozled!
