Not entitled to efile one or more formsets

[kava01]

Any resolutions to this???

Getting same error message.

We could not e-file your return for the following reason:

Our records indicate that you are not entitled to e-file one or more formsets.

Does not show me which formset??  Trying to file a simple free 1040R return for my mom.  She's in Texas, so no state return. Tried signing out, closing window, clearing cache.  Same message.  Any suggestions?
