turbo tax premier 2025 online

I have been using turbo tax for more years than I can count.  I always had a disc and was able to constantly change my data as I worked my return.  Last year I could not get a disc and will not upgrade to windows 11 for another year.  I have always had flexibility with forms and reviewing my return for errors and needed changes.  So because I do not have access to the forms, as I  understand with the online version, an I able to continue working on my return and saving copies online before I actually file the return?  I understand that I won't see the forms, right?  So how can I check my data entries?  I am an 80 year old retired accountant and have always been able to do my own return without any help.  This seems like I am going to be locked in without being able to review my return as I go along and input data until it is time to file.  

 Can someone assure me that I won't have any issues with this new online version?
