Was the T4A reporting a research grant?  Were you in full time or part time education?

This is full time education whole year. I found another answer that suggests that there is a $500 deduction for federal, that doesn't exist in Quebec, thus the discrepancy. I concluded that I should just ignore the warning from TurboTax, but it'd be nice if the software had explained how it came up with the number.

Full time student  received T4A for scholarship is this a taxable income.   I have read that it is not but when I do my income tax its giving me a balance that I owe but I was on OSAP and had no other income.

If this is for a FT Student, then no it is not taxable. To correct this, return to the T4A screen fand move the entry for box 105 to the spot for FT students.
