You should be asking this question in the QB support forum. But it just so happens I know the answer. so here ya go.
In QB select "company" then "company Information". In the upper right click on the pencil button icon thing so you can edit the data.
In the bottom left of the editable window, select the correct "income tax form used". then click OK.
NOte that if you have not previously set up your tax categories correct in QB for the tax form selected, then your imported data WILL BE WRONG! So check your figures after the import.
