Attempting to correct a balance sheet in a forum such as this is difficult as we can't see your return and we don't know what has already been done.
The balance sheet in TT Business is generally manually input. This is not something that the software computes.
I think what you need to do is manually prepare a balance sheet that you believe is correct. When doing so, you need to remember that the S corp made in investment in another business. This investment needs to be recorded on your S corp balance sheet. By way of example, if you contributed $10,000, then the original entry would have been to debit the investment account by the $10,000 (line 9 on the balance sheet) and then credit the cash account by this same amount. Everything balances.
Going forward, each year you receive a K-1, you will need to adjust this investment account by the applicable K-1 line items. By way of example, let's say your K-1 net amount is income, then you will debit the investment account and credit equity. If you have a loss, then you will credit the investment account and debit equity.
