form 8824 Question

Any one?

 

I sold a property on 11/15/2018 and with exchange money hold with an exchange company. New property was identified on 12/28/2018 and purchased on 3/4/2019.  I met 45 days identification and 6 months purchase requirement. 

 

When I did my 2018 tax, I did mention the older property was exchanged when I was working on that particular property under sale of a property section.  But when I checked my 2018 tax, I don't see form 8824, so I probably did not submit it or may have deleted it by accident. 

 

I don't think I can submit exchange info on 2019 Tax since the exchange was initiated in 2018. 

 

So what are my options now? Can I just do amendment for 2018 and submit 8824?  I should have no impact on the tax amount due since I can clearly see I did report the property was relinquished as an exchange.

 

Any opinion would be appreciated.
