Error trying to addliquidityETH in PancakeSwap Testnet

Hi, I'm new to the Solidity development world.

I'm facing a problem, and I would like to know if anyone has a solution for it.

I created a contract and everything is ok I deploy it on (REMIX IDE) and it remains great, but when I try to add liquidity (addliquidityETH) it gives me the following ERROR:Fail with error 'TransferHelper::transferFrom: transferFrom failed ' https://testnet.bscscan.com/tx/0xd5a2c030415b2a2eb427609be342c78da6537d546d9ee6c5b59c9492b7d6fac2

And yes I already did the .approve function and even so this error continues to persist, I would like a possible solution, thank you

Hi your transcation return this error

Transfer amount exceeds the maxWalletSize.

Hi, thanks for the reply, so based on that what function can I add to delete my account (Owner) from my MaxWallet ?

You have to pass address of owner-dev to _isExcludedFromMax

Thank you, my excludadefrommax is active for owner and it still didn't work, what I did was set the maxwallet to 100% and I managed to add liquidity, then I just set it again to the amount I want, thanks!!
