I filed an extension and paid the tax Turbo Tax said I owed. I have returned to file and Turbo Tax says I now $219 more!!! How do I get them to fix this?

Note - when I came back to finish up, I did add in additional deductions I had found, hoping to be able to make it to itemized. I fell short and my return stayed with standard. So, no changes were ultimately made. How do I figure out what's going on?
