There is a MASSIVE amount of "other income" showing in my summary but I can't find where it is. It's not showing in my income section. I'm at a loss.

almost a million dollars in "other income" is appearing and it says I owe $314,000 in taxes. I assure you I didn't earn any other income than what I put in and I can't find it in the system to correct. It's driving me nuts!
