When you enter the second K-1 for the box 2 income, do not enter the box 16 amounts if they don't correspond to the Box 2 income. Same for the Box 1 K-1. Enter the relevant box 16 codes/amount for that income item only.
If you need to start over, delete the K-1's.
If using online version, select Tax Tools, Tools, Delete a Form. If using a desktop version, select Forms mode in upper right corner, then scroll forms list for the K-1. Select, and when it loads on the right side, choose delete form.
