You'll report your 2018 sale of the property in the Investments section under the Personal Income tab. Under Investments, select Stocks, Bonds, Mutual Funds, Other and work it through. When asked, you'll indicate that it's an installment sale.
"I recently sold them and I am “owner financing” them. (Two separate sales). Between the both of them I have received $49K in principal and interest payments. So I still have made no gains."
That's not entirely true. You have interest income to report that was received in 2018 and it is taxable. Even if you're not charging Interest, the IRS taxes you on what they call "imputed interest income" weather you agree with it or not.
