The VA Funding Fee is entered on Schedule A Line 8d as an itemized deduction for Mortgage Insurance. If your Form 1098 from the lender does not have the amount of the VA Funding Fee in box 5 of the form, you will need to contact the lender for the amount.
You will have to amend the 2020 tax return if you filed without entering the VA Funding Fee.
See this TurboTax support FAQ for amending a 2020 tax return - https://ttlc.intuit.com/community/amending/help/how-do-i-amend-my-return/00/27439
NOTE - If the Total of all your Itemized Deductions on Schedule A are not greater than the Standard Deduction for your filing status then the Itemized Deductions will have no effect on your tax return and the Schedule A will not be used.
