How to exclude US savings bond or US Treasury bill interest from WI state tax return

The Turbo Tax Premier script does ask if you have US Savings Bond (or Treasury bill/bond) interest, and then whether you are in about 10 different states, when filling in the Fed  tax return (presumably to help get the interest excluded from state taxes.)  For other states, like WI, it says it will query you later when doing the State returns so as to get the US Savings Bond or T-Bill interest excluded from state taxes.   Turbo tax premier version for WI state taxes did not query me for such US Treasury interest .  So, what I did to circumvent this situation:  I added it in during the Turbo Tax premier tax script as a MISC Subtraction from WI tax.  That generated a WI schedule SB (subtract from income) form .  I then went into FORMS at the top of the WI page to edit the WI SB form.  Line 2 on the SB form is specifically for US Savings Bond and Treasury Bill and Bond interest.  I entered my savings bond interest on SB line 2.  I then erased it from the bottom of the SB form under the MISC option I had originally used.  This US interest did carry over onto the main WI state form.   It's sad that Turbo Tax premier did not query users about such US Savings Bond/T-Bill TBond interest in their script to get it excluded from state taxes.   Did anybody see such a query in the turbo tax script? Please indicate where it occurs if you did see such a query.
