The amount of my refund is less than what the accepted IRS refund was how is that?

[DoninGA]

Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund.

Is the amount sent/issued by the IRS the same as the refund amount shown on your federal tax return Form 1040 Line 35a? - https://www.irs.gov/refunds

If not, then go to this IRS website for information on reduced refunds - https://www.irs.gov/taxtopics/tc203

The IRS will be sending you a letter in the mail explaining what they changed on your tax return that resulted in a reduced federal tax refund.
