Just a wild guess, (I'm not that familiar with PA state returns) but it sounds to me like you may have the same rental property entered twice on your federal return. Go back to the federal and work through the Rental & Royalty Income (SCH E) section again. Confirm there's only one rental property listed. I suspect you may have the same rental property entered twice. If so, delete the one with the incorrect or incomplete data. THen you "may" have to start over on the state return so that it will import again, correctly.
