Thanks for your quick response! My modified AGI for Roth IRA purpose on Line 10 of pub 509-A worksheet 2-1 is 1040 line 11 subtracts Roth conversion (as I have 0 on line 4-9). However, line 1 of TurboTax Roth contribution limit worksheet shows a different number, $4800 less than 1040 line 10. Why? What could possibly cause the difference of $4800?
