After filing with Turbo Tax I found out through IRS that my refund will be less due to a balance. Should Turbo Tax have known this?

Does Turbo tax know about previous balances on your IRS account which will be reduced from your expected return?

TurboTax never knows if you owe back taxes or child support that could cause the IRS to offset your refund.  The IRS knows.   And you should  know if you owe delinquent child support or back taxes.

 NOTE: You can contact the IRS Treasury Offset Program Call Center at 1-800-304-3107 to ask if they have an offset for you on file. TurboTax would not have that information.

TurboTax does not receive feedback from the IRS regarding money that was offset from your refund.  If you owed back taxes or child support, you will receive a letter of explanation from the IRS in several weeks.  The WMR site will contain a message regarding your offset.  It is also possible that the IRS caught a mistake you made and reduced your refund.
