Balance sheet and Trial Balance totals do not match -at all

SUGGESTED

One of my clients' Trial Balance for FYE2023 is showing debit balance of $9,432.79 in Accounts Receivable (which is accurate).

Meanwhile - The Balance Sheet as of 12/31/23 is showing a credit balance of $-4727.48 ???

I've downloaded GL detail for Receivable to check all entries. Nothing's amiss.

Anyone else experiencing this? How to solve?
