Optionally you can leave this screen back to SP, and return to it or just skip into creating a new disposable character. Select the disposable one that's holding the ill-gotten gains you want to legit bank and not flag.
Now from SP, go into Online from the pause menu and Change Character. Once you are done, and remember this is otherwise an unmodded character so is disposable, leave GTA:O back into SP (This just ensures the cash held is stored, as part of the saving of character process). Regardless of which way you go, you can do your perferred generating/spawning money method but it must be cash held, not put in the bank. So working on the assumption you're creating a new main character for an account to transfer, inheriting the existing shared bank balance and will inevitably mod for rank etc once you've pushed funds boosting to a comfortable/acceptable/'safe' degree - delete your old unwanted character (you could just as easily exploit this using character no.2), and start it from scratch by either bypassing the in-game tutorial or working it through. I'm sure many will already know this one, but for those who don't :-Ī pretty low risk way of adding 'picked up' or otherwise obtained 'held cash' of mild and silly amounts to your bank balance, without major risk of it flagging is as simple as.
