How to add my married partner to schedule c

[eachdo]

Married couple own 50/50 sole proprietor business filing jointly.

Turbo tax says I need two schedule C's split between us. 

Tax preparer in the past listed us both in the schedule c.

Is there any way to do that?

Even if he listed both spouses on a single Schedule C only 1 person got credit for it.  You really need 2 separate Schedule C and Schedule SEs.  He did it wrong.

So what happens if our CC Processor issues a 1099-K to one of us. I split that amount artificially between two schedule Cs?

[VolvoGirl]

Yes.  Or you enter the whole amount on the schedule C for that ssn and then enter an expense (probably Contract Labor) for the half that goes to the other schedule C.
