but there are no "segwit wallets" just segwit transactions (may be it just a question of terminology)
When you go to "Receive coins" in OWNR wallets, there are three options.
"Default" gives you legacy addresses, "Compatible" gives you nested segwit addresses and "New" gives you native segwit addresses.
In sparrow, you should select the "Script type" depending on which type of addresses you used in your OWNR wallet.
could you make input BTC transaction to this fresh OWNR wallet and then output it ?
If you generate the correct addresses in Sparrow, you will surely see your transactions.
