I dont see any issue here on QOZ investment reporting in Turbotax. I do my taxes in Turbotax and then a CPA reviews before I submit.
No idea if the step by step interview supports QOZ, but you can certainly make the necessary entries manually on Form 8949. Note that this does not require "overrides" or anything that would prevent you from filing electronically.
Here are the instructions from the IRS pub Instructions for Form 8949 (2019)
[Draft as of October 8, 2019] :
Report the deferral of the eligible gain
on its own row of Form 8949 in Part I with
box C checked or Part II with box F
checked (depending on whether the gain
being deferred is short term or long term).
If you made multiple investments in
different QOFs or in the same QOF on
different dates, use a separate row for
each investment. If you invested eligible
gains of the same character (but from
different transactions) on the same date
into the same QOF, you can group those
investments on the same row. In column
(a), enter only the EIN of the QOF into
which you invested. In column (b), enter
the date you invested in the QOF. Leave
columns (c), (d), and (e) blank. Enter code
“Z” in column (f) and the amount of the
deferred gain as a negative number (in
parentheses) in column (g).
