TaxAct® supports the entry of up to 100 Forms 1099-INT.
Form(s) 1099-INT is not transmitted electronically with your return; only the amounts which transfer to the Schedule B (Form 1040) get transmitted. If Schedule B (Form 1040) is not required to be a part of the return, the total amount from all Forms 1099-INT will be reflected directly on the Federal Form 1040.
