I think you may be entering the form 1099-NEC's as though you have a separate business for each form, as opposed to one business but ten different forms. If you only have one business and received ten 1099 forms reporting income for it, you should just add one business in TurboTax, then all of the 1099-NEC's under that one business.
Otherwise, you will need to combine the entries and then mail your tax return in.
