Business & farm

I need to enter a negative number on Line 7 of M-2. I'm trying to correct an incorrect entry on my balance sheet which shows the security deposits $45 less than they should be. I need to increase the *negative* retained earnings balance by $45. I have not been able to figure out how to do that. I was told to put in correct security deposit on Schedule L at line 18 and then report it on M-2 as a draw/distribution. But the program will not allow me to do that. Line 6 is a negative number. Our Schedule Ks are negative (show losses). What am I to do to get my balance sheet in balance if I can't enter a distribution on Line 7 of M-2 to increase the Liabilities section?
