Well done for getting to the end of your IVA. I would phone GT and confirm that you only have one payment left to make.
Once you have made that payment then you can cancel your payment and then you have to wait for the closures team to tie all the loose ends up and then you will be issued with a closure letter.
Even though the IVA will remain on your file for the full six years, check your credit files with Experian, Equifax and Call Credit and make sure that there are no defaults registered after the date of IVA acceptance. If so, once you get your completion letter, you need to write to any creditors who have defaulted and get them to remove those defaults.
