I assume you are filing Schedule C? I guess you could enter the full amounts as income, including the duplicates. Then enter a misc expense for the duplicates saying like same income reported on two 1099K.
Are you using Deluxe? You can enter Self Employment Income into Online Deluxe or Premier but if you have any expenses you will have to upgrade to the Self Employed version.
