TTX "Onlne" Does offer a way to upload the "prior" year's full .tax2019 datafile, with all it's details, into the 2020 Online software. You just can't upload a 2020 .taxfile into Online 2020
So you should be able to do want you want and get all the details....but you'll hate the Online software if you've been using desktop for years. (no "Forms Mode" , and the interview flow can get convoluted)
