Who advised you yo buy the Business version? That is to do a partnership return to create the K-1. Not if you are receiving a K-1. As you found out it does not prepare personal 1040 returns. You could have bought any personal version, Basic, Deluxe, Premier or Home & Business.
You can try asking customer service. (You need to pick the CD/Download program in the product drop down box.)
