I presume you are talking about your Deason adjustments to expenses. TurboTax does not allow for the attachment of PDFs in this case. You can either file without the attachments and keep them with your records in case the IRS asks questions about your expenses, or you can file by mail. A tax professional may also be able to include attachments in situations where TurboTax can’t. This is not a limitation enforced by TurboTax, it is enforced by the IRS. The IRS puts constraints on consumer level software that are not imposed on professional software.
