Ok using your amounts. They took 20% out for federal taxes and probably 8% for state taxes.
The $427 taken out equals
1,527 x 20% = 305 for federal
1,527 x 8% = 122 for state
So your withholding on line 16 is
$2,528 + 188 + 305 = $3,021
And Check your state return. The state withholding should be $122 more than your W2s.
