I will advise you to import the private keys using the electrum wallet,
verify the wallet before using and make use of the manual fees option.
Instead of just importing the wallet into electrum, it would be better to create a new wallet on electrum and send all the fund to that.
Also note that trustwallet allow you to adjust the fee rate manually too.
I am not used to Trust wallet and I could remember I only used it twice which I believe was before the acquisition of Binance. However, the problem OP had has to do with the wallet being a transaction fee and sending the BTC to electrum first before moving it to where he was to send it to will attract more fees. I suggest he try what was explained
