What kind of error?  Did you check that there are indeed 330 days within the qualifying period by your own calculation?  If so, how does your calculation differ from what's in PS?

PS (as with other tax products) generally relies on your input to determine the qualifying period.  If something in PPT is wrong, it usually lies with the input.

I have been doing this for 25 years and I know what to input so that is not the problem. 

And yes the dates are in there.  This problem just popped up today.... Have already filed tax returns with the 2555 in the past few weeks. 

Sounds like a software issue as there have been three complaints today already.

@IntuitAustin @IntuitAlicia Did an update break F.2555 in PS?  Thanks!

The solution seems to entail either waiting for a correctional update or delete the 2555
