How to change the tax charge/refund

Simple question - how do I change the income tax expense/income tax refundable from the amount that BGL calculates to the amount I calculate?
I tried a journal entry, but after “Create Entries”, the BGL amounts remained the same in B/S and operating statement.
This is my second year, but forgot how I achieved the correct result last year.
I prepare annual report and tax return manually and the fund auditor relies on my hard copy records.

A simple response would be to identify the transaction(s) that are causing the discrepancy then have a look at the tax label for the account involved in chart of accounts under “more detail”. There are a range of Expense labels that might be appropriate for the specific issue. Best approach to find the problem entries…

Another way is to utilise the tax adjustment section of the period compliance prior to creating entries.
