1099 or Up-to-Date Revenue Reports for Tax Filing

As a marketplace seller, I get a seller report every once in a while (usually a few months later.) I am trying to file income taxes and noticed that I did not receive a 1099-MISC from Epic. Should sellers expect to receive one? Also, since revenue report come in a few months later I don’t have all of these reports for 2016 yet. These two factsmean that I am currently unable to accurately report this income on a personal tax return. How are marketplace sellers expected to handle this?

One additional question: are marketplace seller earnings reported to the IRS using a 1099?

1099’s have been sent out to domestic marketplace sellers. They were mailed out by the deadline of 1/31/2017, so they should be arriving any day now.
