Turbotax is telling me I can't e-file form 568 due to one of the listed conditions--none of which exist best I can tell (the software makes it incredibly difficult to review the form or the associated schedules). How can I get past this? Is it just a missing feature and not related to contents of the form after all?
I can't help you get past not being able to e-file, but I can tell you how you can review Form 568 and the supporting schedules. If you want to review your return you will need to pay for TurboTax and then you will be able to print your entire return or specific forms/schedules prior to filing. You will still be able to make changes prior to filing. Follow these steps to print a preliminary copy of our return in TuboTax Online:
Note, you must pay by credit card in order print or preview your preliminary return. You will not be able to pay using your federal tax return.
