I opened an HSA in 2019 but had a qualifying HDHP in 2018 as well as 2019. Can I make a contribution for the 2018 tax year even if I opened the HSA in 2019?

Yes, you can.

Please see TurboTaxMarilynG's excellent explanation below on what you'll need to do on your tax return to reflect this contribution..
