profit/loss/1099.....

I need some help. I am trying to move from the house I own to renting. This is the first yr that I have not worked, am able to profit from my self employment. I am being asked for a 1099 for proof of income and I am confused. The turbo tax product I use just gives me a Profit/Loss statement, not a 1099. his is really important as I signed a new client and am making more than enough.  Is a 1099 just something I can make??? If I make one up, do I have to file it right now??? Or do I have to wait until next yr to move? Not everyone is ok with a profit and loss statement. Please can someone direct me on how to show proof of income??? Thank you, In advance
