I had to mark the basis as adjusted because it was missing on the 1099-B. The basis was not reported to the IRS at all. The values were in the short term section, not reported to the IRS.
The confusing thing about the message is that the message says "if the 8949 was not sent electronically". My question is, was my 8949 sent electronically? Which would mean I don't have to mail it?
