Thanks so much for such a quick response.

Yes, the kids all have the same last name and no hyphenated names.

And just today, my clients called SSA and confirmed the information on their return matches what is in the SSA database.

This is the 3rd year in a row this has happened.

For the first 2 years, we had to file paper returns, which were processed as filed without issue. But the refunds were significantly delayed.

I can't tell if this is an issue with Intuit's e-file processing or with the IRS.

And the ProSeries system does not even identify which of the kids data is not matching.
