VAT is not showing when I record supplier expenses, even though tax seems set up correctly. Expenses appear with zero tax, which may affect reports. How can I fix this?

I need assistance with QuickBooks. My business has supplier expenses that include VAT, and I want to record them correctly in the system. However, when I capture these expenses in QuickBooks, the VAT option does not appear. As a result, the expenses are being recorded as though no tax was charged, which could lead to inaccurate financial reports. I believe my tax settings have already been set up correctly, but VAT is still not showing on the expense entries. Could anyone please advise how I can fix this so that VAT is reflected properly on expense transactions?
