I have two credit cards and I mixed the 2 payments, if I'm one day late fixing it, will it count on my credit score?

Like let's say card A was supposed to get XYD and card B was supposed to get CDF in payments. If I mix the two debts together and pay each card the wrong amount but correct the problem within 48 hours, will I still have debt for unpaid bills when the next credit cycle comes in? I read on one website that debts are not tabulated until it's been outstanding for 30 days and I read on another website you're penalized even for being 24 hours late. I use TD if that matters.
