Do you have any resolution about completing Form 8997 with 2018 deferred capital gain?  I have similar situation.

Taxpayer realized capital gain in 2018 from a partnership interest and made an investment in a QOZ fund in June 2019 (within 180-day after 12/31/18) and took a capital gain deduction in 2018 on Schedule D/Form 8949.  In completing the 2019 Form 8997 (which is a new form for starting 2019), should this transaction be reported in Part I Total QOF investment holdings at the beginning of tax year with the date QOF investment acquired in June 2019 OR should it be reflected in Part II current tax year capital gains deferred by investing in QOF?

Any clarification and insight would be greatly appreciated!  Thank you!
