The 2020 1st is conditional on Karlsson being on an Eastern Conference roster during 2018-19.
2020 NHL Entry Draft Pending Transactions
That pick won't transfer, so the Sharks will have it.
If they sign Karlsson to an extension or make the Cup Finals, they'll lose their 2021 1st though and then wouldn't be able to use an offersheet.
Here the full trade with conditions. The 2020 1st is for the Sharks making the playoffs. IF Karlsson ended up on an Eastern Conference roster it would have been an additional 1st before 2022:
Ottawa Senators Acquire:
Dylan DeMelo
Chris Tierney
Rūdolfs Balcers
Joshua Norris (Signing Rights)
2020 conditional 1st round pick* (SJS)
2021 conditional 2nd round pick** (SJS)
2019 conditional 2nd round pick*** (FLA - #44)
conditional 1st round pick****
****Sens receive a 1st round pick from the Sharks (no later than 2022) if Karlsson is on an Eastern Conference roster (reserve list) during the 2018-19 season.
*Conditions: Ottawa receives Sharks 2019 1st round pick if Sharks do not make the playoffs. If Sharks make the playoffs, Ottawa receives Sharks 2020 1st.
*Result: Sharks made the 2019 playoffs, Ottawa receives Sharks 2020 1st round pick
**Conditions: Sens receive Sharks 2021 2nd round pick if Karlsson is re-signed. The selection upgrades to a 2021 1st if Sharks reach the Stanley Cup final in 2019.
***Conditions: 2019 2nd round pick is the higher of the two picks the Sharks currently own: Panthers and their own.
Result: Ottawa will receive Panthers 2019 2nd round pick.
