I have my 12 phrase but I am not able to get my trust wallet back
You insert all of them in the order you wrote them down - assuming that is the same as the order they were shown to you by the wallet when you wrote them down.
See https://community.trustwallet.com/t/how-to-restore-a-multi-coin-wallet/43

Step 1 - Launch Trust Wallet
Open Trust Wallet and then tap on Settings.
Step 2 - Access Wallets
In the Settings screen, you will find here Wallets. Tap on it to display the wallets that you currently have. Tap on the “+” sign on the upper right to access the Import Screen.
Step 3 - Access Wallet Import Screen
Since we are trying to restore a wallet, select I already have a wallet. Then, tap on Multi-Coin Wallet.

If you don't want a multi-coin wallet it appears you can just select Bitcoin.

Step 4 - Input the Recovery Phrase
Almost done. Carefully type the recovery phrase, put in the name of the wallet. Tap on Import.
