OMIGOD. I am such a bonehead. While wrapping up this year's return I happened to go back to 2004 to reference something and noticed a MAJOR bonehead typo on our personal CA return. Lucky for me, filing an amended return will get quite a bit of money back!
From now on I'm gonna pay the pros to do this stuff. It's just getting too complicated. I already farm out the 1120's and 5500's etc. but had been doing our personal returns by hand in earlier years and then via TurboTax the last 3 years.
Yikes...now I'm wondering if I may have honked up anything else significant.
