Sadly this was never fixed from last year and still exists this year. I have a work around. I enter the 1099 twice; once with all information EXCEPT I only enter for the tax exempt interest, the PA portion, then on the next 1099 I only enter the remaining amount for the multi-state tax exempt interest. Together the "two" 1099s are equivalent on the Federal return, and on the PA State return the tax exempt PA interest should come through properly. Good Luck.
