@Macy522 As long as your payments are there before the filing deadline, you should be good. The IRS will apply your payment to your tax account, so the payment will be there whenever your mailed return arrives and is processed. I'm assuming that the states work in a similar fashion.
If there are errors in your returns, taxing authorities will notify you by mail regarding any changes they make. If you owe additional money, they'll notify you and you can then make payment.
