I was able to get it to work last night using what's recommended in JamesG1's post above. I am not self-employed but use schedule H for nanny tax.
Steps:
-Change tax withholding on my W-2 to something low so there's something owed rather than a refund.
-Go into the self-employment tax deferral section. Enter 0 for eligible income, then 0 for amount to defer.
-Change tax withholding on W-2 back to the correct value.
-Go through the review process again.
I was able to e-File and my return was accepted within a couple of hours.
