I can't set the limit that the contract accumulates tokens to exchange for BNB


My contract is a safemoon fork. He must tax transactions, accumulate some tokens and sell these tokens by BNB to send to the 4 wallets in the code. Turns out he must sell the tokens when he hits a limit and he's not doing that. Although the contract is exchanged for BNB, I don't know the amount he uses for the exchange. I would like to set a limit for it to switch, because the contract accumulates a very large amount of tokens.

How to solve this?
