I did a Like-Kind exchange in 2020 do I indicate that I sold the property in Form 4797 AND fill out a Form 8824...or just Form 8824

For a like-kind exchange, form 8824 has to filed in ADDITION to form 4797.

You will find that a Form 4797 will not be generated unless you received boot in the exchange.

Ok  so if I received no Boot (e.g. all proceeds from relinquished property are applied to new property), then no 4797 is used...correct?

But how do I answer the Yes-No question in TT if I disposed (Sold) of the property....Yes or No.  If I respond Yes, TT assumes I sold it and generates a capital gain??

By filling out Form 4797 (when I answer the Yes-No question in TT if I disposed (Sold) of the property), TT assumes I sold it and generates a capital gain. 

And Form 8824 does not seem to nullify the capital gain generated in Form 4797...or does it?  I seem to be "missing" the link between the 4797 and the 8824

Correct: No boot equals no 4797.

Why are you "filling out" Form 4797? You should have checked the box indicating you had a like-kind exchange.

Thx = your right - I should not be filling out the 4797.  Didn't know what I didn't know...have sense found the button for like-kind exchanges

Did anyone answer this?  I can't seem to delete the gain from 4797.  The 8824 is accurate but I am showing a gain too.  

Can you check Form 4797 in Forms Mode? Are there entries in Part III?

Yes, that's where the gain is being calculated.  I thought there would be a way to indicate that the gain was deferred but can't figure it out. 

You might want to save your .tax file and then try deleting those forms and re-entering the exchange information. Something must have gone wrong during the input of the transaction.
