Autosaves are generated at roughly 9 in the morning and are charged at 3 pm. You're welcome to edit or cancel saves at any point during this window of time.

When a save generates you will be able to find it at the top of the home page and in your Savings tab. Just go to Savings, then select the account your autosave is set to go into (if you're unsure of this, you can check by going to Profile > Savings Plans > Auto-save Settings > Autosave Allocation). The save will be listed along with the rest of your transactions. Prior to 3 pm, you'll see an "adjust save" button to the right of the transaction amount - click this, and you'll be presented with the option to "skip save".

To adjust your save, find it at the top of the home page or in the Savings tab as explained above. Once you've located the save and clicked the adjust button, you can enter a custom amount for the save to be changed to.

Once you save this change, the amount you've specified will be charged.

Should you wish to skip several or turn off autosaves altogether, please find more information here.
