Do I have enough time to do this?
Impossible to predict with any certainty but it's likely you will miss your connection.
Delta closes the check in for international flights 1 hour before departure https://www.delta.com/us/en/check-in-security/check-in-time-requirements/international-check-in
Incheon Arrival procedures are here: https://www.airport.kr/ap_cnt/en/arr/entmap/t1/ent_t1.do
So you have only one hour to
Baggage time and immigration/customs time vary a lot and are notoriously difficult to predict with any certainty. It certainly helps if you have status with the airline, fly business, or have some other means of getting priority treatment.
If all things work really well, than you have a chance of making it, but the odds are 50/50 at best.
Please note that if you miss your connection, you are entirely on your own and may have to buy a completely new ticket on the spot. As far as Delta is concerned you are a "no show" by your own fault.
I strongly recommend against this. Rebook, if any possible
