It means you're not bound by the 1098-T. But, you need to understand what really happened and adjust accordingly.
It won't interfere with the previous tax year, if you reported the previously year correctly. If I understand your situation correctly, all you need to do is enter the amount from box 5, that applies to the 2019 charges, in the box "amounts not awarded for 2020 expenses", in the scholarship section.
But a simpler solution would be to just change the box 5 amount when you enter it.
