2nd time Amending using Turbo Tax not working, and Can I file my current year tax before I do the amend for last year ?

I have following questions, can somebody please help answer. 

1. I need to amend my tax return 2nd time for 2023, is this possible in web version of Turbo Tax or should I need to get a Desktop version?

background: Back in march 2024, I had to amend my 2023 tax return and it was successfully processed. I just found a 1099R for a rolled over retirement account from 2023 and so need to amend my 2023 tax return again. I tried to do this on web version of Turbo Tax (2025). And the numbers do not look right as well as Turbo Tax goes into an error loop and does not show what the actual issue is. I connected to an agent on Turbo Tax and after some time of troubleshooting I am advised to purchase a Turbo Tax Desktop version for 2023, then import my 2022 tax filing document and redo the 2023 tax return and to then amend it. Is this accurate?  It's a lot of work so wanted to confirm before I go down this path.

2. Also, Can I file my tax for 2024 before I do the ^ amend for 2023? If it's possible,( I guess), I will have whole year to figure out how to do another amend for my 2023 tax.
