TP1 - Line 252 - This is calculated automatically by TurboTax, based on amounts you have entered through the T-slip and relevé slip entry screens.
As quoted by RQ “The amount you carry to line 252 cannot exceed the difference between your investment income and your investment expenses. The unused portion of the adjustment of investment expenses is equal to the total of the amounts entered since 2004 on lines 40 and 64 of Schedule N, minus the amount already used to reduce your investment income for a previous year.”
