I cannot efile to due incorrect formsets. What am I doing wrong?

[JoannaB2]

Yes.  It means that one or more forms aren't available to e-file yet.  The IRS is still finalizing some tax forms needed for electronic filing. You may do the following to check for errors:

1.  Click Federal Review located on the upper right hand side of the screen .
2. Click review to each details ,and it will take you to form 1099.
3. You do the same on your state income tax. 
4. When done fixing, go back to Federal Review to check if the return is ready to e-file.

See, federal forms availability, link.
