1099-R traditional IRA roll over to Roth IRA question (2019 taxes)

In 2019 I opened a traditional IRA (first time, never had Traditional IRA before) , transferred post-tax money into it from my regular bank account in Feb-2019 and within a week rolled over the complete money from Traditional IRA into ROTH IRA (which I had already created with funds in it for couple years via post tax contributions ).

Q#1 : Do i need to file form 8606 ( via mail-in) before i enter the 1099-R (2019) details into TT for filing 2019 taxes?

Q#2: Does TT allow me to enter form 8606  or i need to file form8606 separate? I have not used TT to file my 2018 taxes rather I used a tax prepares help to file my 2018 taxes. Is the form 8606 to be filed as an amendment to my 2018 tax return?

Q#3: Can I enter the 1099-R (2019) details into TT without filing form 8806 (for 2018)?

thanks in advance
