I am receiving an error when trying to attach documents to the PA state 1041 amended return. The only option in the drop down box is "other" which produces an error. Please fix the issue.
I also got this error when attaching a pdf file containing stock trade information to the Amended PA-41. But I was able to E-File the return by turning off Error Checking. The return was accepted by Pennsylvania. However, I agree that this error should be fixed.
