Deductions & credits

@Superann What do you see on line 12 of your Form 1040?  Is it your standard deduction amount or a different amount?     You say that the "refund number will not change."   Is your refund amount equal to -- or less than -- the amount of tax that was withheld from your income?   Maybe you are getting back as much as you can possibly get back.
