A little trick to this method. There are 3 forms generated for the 2210 delete option.
(Browser TT Filing, not stand-alone software)
Start by deleting the first one only "Form 2210". it will then prompt you that this will remove all 2210 forms from your filing. Select [Continue], and this should clear all 2210 forms out, and you should be able to progress with your e-file immediately afterwards.
