I have a 1099-NEC from the state of Iowa for a retention bonus that was given to all teachers. This is supposed to be state tax free. How would I add this to my return?

When amending the return, turbotax only gives me the option to add a business and count this as self employment tax. This was paid to us by the State of Iowa not any specific business, so I'm not sure how to add this correctly. Thank you!!
