On one level it's not how you filed, but how you had a refund returned to you. I just today mailed in my 2019 return. I also today received that $1,200 as a direct deposit, because for 2018 I mailed in a paper form but had my whopping $5.00 refund done as a direct deposit to that same account.
I'm sure there are other permutations, but regardless of how you filed and if you have or haven't filed 2019 yet, if you received a refund from 2018 as a direct deposit you'll get the $1,200 DD'd to that same account.
