My situation was not as complicated as some. I had no debt.
Really, I'd try to find a CPA experienced with DST's and let them do it the first year. It took me a lot of time and I didn't enjoy the process. I bought 5 replacement DST's (which I would not do again). You set up each new DST as a separate rental and pick up the year end figures provided by the sponsor on the schedule E for each asset. For depreciation, you have to set up each DST on their own schedule. And there is an election you can make to treat it all as a new asset, or the default is to carry forward the old depreciation and set up any additional paid as new asset depreciation. The sponsor again should have provided you with values for depreciation. They do not give you details about cost segregation, just land and buildings. In my case that would not have been material so I didn't bother asking for it, but you could.
In reporting the 1031 exchange you have to show the allocations to each new DST.
It is very important to file on time or extend your return and file by the extension date or your exchange can be invalidated.
Finding a good CPA experienced with DST's is not easy, you have to ask them what their experience is with 1031 exchanges into DST's, and multiple ones at that.
Good luck. In the future I will keep my exchanges simpler. I would not count on Turbo Tax "telling" you how to do this. And I ended up filing paper as I had elections to file and did not agree with Turbo Tax on the QBI election statements.
