Fill something wrong in 4868 form

[lbzsmt]

When I fill 4868 form. I think I fill a number 544.2, but when I download it, it seems like 5,442? What's wrong? Can I modify the form. It is already accepted. Can I re-submit the form?

go to www.irs.gov/payments and "Make a payment"

select Reason: Extension

pay any amount  (your intended amount would be good here).   your request is automatically approved.

Make a note of your payment  amount so you can claim credit for that.

Thanks, but I think I don't own tax in 2018. Should I still pay some amount?
