Get your taxes done using TurboTax

When TT asks about annualizing income - it says put your AGI for 1/1-3/31, then 1/1-5/31, then 1/1-8/31, and finally the whole year. How do you figure your AGI? I put in my wages for each of those periods, and that's when the $276 owed showed up. And if I check box C and let the IRS figure my tax penalty - that could open a whole can of worms. What if they decide I owe more? How could I ever get in touch with the IRS? I've been down that road before. Better to suck up $11. I guess instead of putting the proper number of exemptions on my W-4s, I will need to reduce that number. I thought I had already done that. Of course, trying to see one's W-4s seems to be next to impossible.
