Turbotax insists on putting my name in schedule k-1 on line H 1 d, then tells me that there is an error on that line. I cannot figure out what they think belongs there

The actual line number on the K-1 Worksheet is H(3)(d). To resolve this, you need to choose the QBI Component worksheet that applies to this property. If you have multiple activities that used your name, this choice may be difficult. Try each option presented to you until the program accepts one.
