Well, firstly, you could file now but pay later.  

Otherwise, the IRS says they plan to make a web site where people can provide their banking info, but it’s not ready yet.  

I filed our 2018 taxes but not with Turbo Tax

You're fine. The IRS has said they will use data from the 2018 tax return if you haven't yet filed your 2019 return. So if you took direct deposit on your 2018 return and that bank account is still active,

you have nothing to be concerned with.
