After you file

Not sure what you are amending or why----but in general the only reason you would need to enter a state refund you received would be if you itemized deductions on your tax return----like mortgage interest, property tax, etc.  and received a state refund.   If you itemized then the state refund you received was taxable income.   If you just used your standard deduction, then the state refund is not taxable.
