Error check on turbo tax is telling me to fill in a taxable amount on the 1099-R. On my form the amount not determined box is checked. This is a gross distribution from an inherited IRA (from my father) and is a RMD. This was taxed as part of his estate and 45% of the amount is deductible, although it's swallowed up by the standard deduction. As an alternative can I subtract the 45% from the gross distribution and enter it in the taxable amount box?
