According to your post you did not convert it to business use ... you used it for family (personally) and then took time to fix it up and then sold it.
Your basis is the original purchase price + cost to purchase + improvements (fixes) + cost of sale.
Sales price - basis = profit or loss reported on the Sch D.
A second home is a personal use capital asset. A gain on the sale is reportable income, but a loss is NOT deductible. You may receive IRS Form 1099-S Proceeds from Real Estate Transactions for the sale of your home.
To enter this sale of a second home in TurboTax Online or Desktop, please follow these steps:
- Once you are in your tax return, click on the “Federal Taxes” tab ("Personal" tab in TurboTax Home & Business)
- Next click on “Wages & Income” ("Personal Income" in TurboTax Home & Business)
- Next click on “I’ll choose what I work on” (jump to full list)
- Scroll down the screen until to come to the section “Investment Income”
- Choose “Stocks, Mutual Funds, Bonds, Other” and select “start’ (or “update” is you have already worked on this section)
- The first screen will ask if you sold any investments during the current tax year (This includes any sale of real property held as an investment property so answer “yes” to this question)
- Since you did not receive a 1099-B, answer “no” to the 1099-B question
- Choose type of investment you sold - select Second Home
