I had the same issue. I got a refund for two years in 2016. Now I am being charged interest and penalties all the way back to 2014 even tough I got the refund in 2016. My phili age tax refund was $2005 but now I owe NJ $2163. I'm pretty miffed that turbo tax did not pick this up, since everything was entered correctly. I no longer have the confidence in the program I once had. And I also have to immediately re-file 2015 2016 and 2017 to get ahead of the next audits. Not happy.
