Deferred tax opening balance

The trial balance of Highwood at 31 March 20X6 showed credit balances of $800,000 on current tax and $2.6 million on deferred tax. A property was revalued during the year giving rise to deferred tax of $3.75 million. This has been included in the deferred tax provision of $6.75 million at 31 March 20X6. The income tax charge for the year ended 31 March 20X6 is estimated at $19.4 million. What will be shown as the income tax charge in the statement of profit or loss of Highwood at 31 March 20X6? I have no idea why the Deferred Tax T- account have. Debits: 6,750 carried forward I thought it was the DTL and the opening balance is credit Please help me.
