Amending is always an option.
But I don't see where indicating the filer is the only owner in the TT input form translates into the exact same on form 5695 since this form uses the term occupancy for box 32a which is checked or unchecked depending on response to said owner question in TT.
There is another part of form 5695 that does specifically use the term owner. But that is under Part II Section B ("Joint Ownership of Qualified Property") where expenditures on qualified property are shared with a neighbor to benefit each of their main homes. But in this case owner relates to neighbor's ownership of shared energy property expenditure and not actual home ownership.
So it seems there are two situations where apportioning credit is needed. 1. Where neighbors in separate homes that expend money on a shared qualified energy property. 2. Where multiple occupants in the same home have expenditures and need to apportion credit accordingly. But #2 does not specifically say anything about ownership that I can see.
It seems like for TT to guide a taxpayer through this form requires more questions and sub-questions before box 32a should be checked or not.
Everyone should check this out for themselves. I am just pointing out what I see and think.
