I am doing this now also; an RDP couple in California.

I prepared a MFJ return. For CA, you do the Married/RDP return and efile it? Will it efile without a Fed return that also efiles?

For the IRS, I did two single returns which both have the 8958. How does this work with the W2s? Both taxpayers have wages with withholding. Obviously the two single returns will not report what is on each single taxpayer's W2. Or does the 8958 take care of that discrepancy?
