You don't specify which form of business or return you filed. But for C Corporation, Form 1120, the balance sheet on the return is the BOOK balance sheet.
I'm not at all familiar with TT balance sheet. However, in my years of auditing, I've reviewed many balance sheets and the reconciliations of income per books compared to income per tax. Generally, there were not two different balance sheets, only book balance sheets. Differences were in book income vs. tax income. Talking here in generalities is pretty hard to come up with explanation for any differences.
However, first, 2017 and 2018 must be handled in the same manner.
Second, do you have differences between the way you report income and expenses for book and the way they are reported for tax? If so, Sch M-1 on Form 1120 must be reconciled. Also, Sch M-2 is for books, and can help to reconcile any differences.
You mention getting things to reconcile with the "numbers in the bank". I'm not sure what you mean by that, if you're actually trying to reconcile to the bank balance of accounts? If so, you've got to reconcile the cash received but not deposited from sales. Also, taxes "reported" appears to be different than taxes paid. Depending on how you've entered things in the accounting system, that also needs to be reconciled to "bank balance".
Thus, you do have some a/r and a/p based on those items alone.
Beyond that, I don't think I can help short of reviewing all of the information which is not a possibility in this type of forum.
Perhaps other users have a better answer.
