I have already entered income (W2, 1099-R, 1099-DIV, 1099-INT). I don't know why you did not see that on the file. The only income that remains to be entered is my 1099-B, and when I attempt to enter it, I get the same error message as I do for the loss carryover (screen shot in original post).
Your answer that I have no income entered is incorrect. Please look again at the file.
