An NOL (Net Operating Loss) is a negative overall income for this or a prior year. It goes on your return as a negative and reduces your income. If you had a negative income in a prior year and carried it into this year then the explanation would be "NOL carryforward from prior year".
If you have not used a negative number intentionally in your preparation of your tax return then you need to go back through your federal return and see why it thinks you have entered a negative number.
Yes, I understand NOL. Turbo tax is asking me to upload Federal NOL deduction detail:F500P1 as an attachment before I can efile the Virginia state return. My question is what is F500P1? Does it stand for Form 500 Page 1? Do I print it from the return first and upload it as attachment?
That is a state form and you probably just need to enter your NOL explanation into the state form to match the explanation on your federal form.
I have the same issue; how did you solve it? What form was attached? Do I upload the Net Operating Loss Worksheet from the Federal as attachment?
