What wallet software you are using at?
OP already said that he/she is using Safepal.
From the look of things, Safepal is a close source wallet although they didn't state it in the site but from the articles I read and my own understanding, it is a custodian wallet.
You are right that Safepal is close-source, but it's not a custodial wallet. Safepal is non-custodial and give you access to your private keys.
As Nwada001 said, if it is an Electrum Wallet, Op just need to clink on the particular transaction and copy the send address and resend back the money to the sender.
OP is asking how to spend a particular UTXO and it's required to use coin control for that.
