No, there is not a issue with TurboTax. You have seven pages Form B and 1 and only three pages of Form A because the IRS has created a layout where Form A can accommodate three copies of Form 1099-NEC on one page. Form 1099-NEC Sch A is printed on a single page is that it is intended to be attached to Form 1096 and submitted to the IRS.
On the other hand, Form B and 1 are printed on individual pages for convenience in distributing them to the recipients.
