Get your taxes done using TurboTax

If your qualifying expenses were less than provided by the church you would enter the lower number, since the amounts spent on non-qualified expenses becomes taxable.  As long as your expenses were equal or more than the provided amount, you would enter the same number in both boxes (you don’t get an extra tax break if your expenses are more than the allowance.  You would have to ask the church to change the designated amount.)
