sorry I posted in error with no details and you replied really quickly to the title only! I did see I could enter it as a payment made with an extension for 2019, but the payment was made for my 2018 taxes but not used in that return. I do get the $150 credit if I enter it as paid with a 2019 extension but I'm not filing an extension for 2019 - hoping to get it done on time this year!
