Line 1 on the 10401 k-1 is ordinary interest income. Line 14 a is TE income. They are two distinct items.

In my dummy return, I entered your two items on the k-1. On 1040 line 2a was $720, and one line 2b was $736. Only line 2b is added into income on line 6. Does your line 2b show $720+$736=1,456?
