I e-filed my return but I just noticed that there is no deduction method checked and line 17 is blank. It should be 2700.00 the standard deduction. How do I fix this?

it goes from my AGI line 16 to line 18 as the same as AGI the on line 19 it takes the exemption for single of 3,200 BUT its should also apply 2700 as a STANDARD deduction on line 17
