IRS requires all closing transactions to be detailed on form 8949 or on your equivalent form (i.e. spreadsheet ) with the same information and in the manner of Form 8949.
Your sales category should be C or F since you don't have a 1099-B.
There is no exception for those sales categories.
In this case, TurboTax is failing to remind you that you have to mail the transactions details within three business days of your e-Filed return being accepted.
