Are you the paid tax preparer?  You should not be entering your Social Security Number as the preparer information (and there isn't really a place for it anyway).  Are you referring to where you enter your PTIN?

Yes, I'm a paid preparer. I'm not talking about my PTIN. That is where it should be.

My business does not have an EIN number, so I put my social in under Firm Information, and now I'm getting an error on the return because my SSN has double zero and it is telling me that it shouldn't. I get that if it was an EIN, but my business is run under my social.

You would never use your Social Security Number.

I don't use ProConnect (I use ProSeries), but I don't enter an EIN.  Just the PTIN and it doesn't have any problem.  I'm not sure if this matters, but did you check the self-employed box?

There's not box to check that I'm self-employed. I will have to try calling them. Thank you for your help.

This is the error that I have in the return:

If you don't have an EIN, you shouldn't be entering anything there.  Have you tried leaving it blank?
