Use the steps for vacant land. Even though you were allowed to report this as a like-kind exchange, land is not a depreciable asset and therefore is not reported on Form 4797, but rather on Form 8949 and Schedule D. (Capital Gain investment transactioon).
Are you currently using Section 1031 like-kind (purchased more land in 2018), or was the like-kind election made previously, and now you sold the property?
A better question would be, how do I enter the information in Form 4797, line 5, using Turbotax?
