does anyone know what the minimum income requirement (to file returns.)is, in order to apply my deductions....

Answer 1

For a single taxpayer who is not the dependent of another taxpayer, you must file a return if your wages exceed $8,450, you have $400 or more in self employment income, or $850 or more in unearned income.

The standard deduction for a single taxpayer is $5,150. You'd need more than that in itemized deductions to make itemizing worthwhile.
