Guys, could really use your help and expertise here.  I found a paper wallet I made with a 12 word seed from bitaddress.org back in 2018.  It's not got much, but it'll cover some bills.  So I already have a Coinbase account.  What's the safest way to get the paper wallet into Coinbase?  I downloaded Coinbase Wallet on the Apple store, and when I run the app, it asked if I had a 12 word seed.  I thought 'this is too easy' and wondered if they meant a 12 word seed from some other wallet program, not a 12 word seed from bitaddress.org.  Also, from my account on coinbase.com, there is no import paper wallet or load private key option.  And one more thing, the receive address for my coinbase account starts with a 3 and my bitcoin address starts with a 1.  Is there some incompatibility issues I need to be aware of?  Finally, I heard that bitcoin 'forked' once or twice and I might have more coins than just bitcoin??  How's that work for sweeping my paper wallet?
