Deduction for consulting services to write a book

It depends. You would need to report the sale of this book as self-employed business income and expense. In addition, since this is a freelance contractor and if you paid more than $600, you must issue a 1099-NEC to that consultant. To create these, you will need to upgrade to Turbo Tax Self-Employed and then follow these instructions.
