Craig Westcarr's equaliser forced extra time, Lee Hughes put County ahead but Wes Morgan equalised for penalties.
League One County made the brighter start and took a deserved lead when Edwards slotted home Alan Sheehan's cross.
But Steve McClaren's men fought back and pulled level on the half-hour through McGugan's curling 30-yard free-kick.
After the break, Martin Allen's men seemed rejuvenated, but Findley slotted home Andy Reid's left-wing cross to put the hosts ahead.
But substitute Westcarr pulled County back into the game just five minutes after coming on, taking the game into extra-time.
After eight minutes, Lee Hughes looked to have secured a shock victory for the visitors when his thunderous right-footed shot went beyond the reach of keeper Paul Smith.
But Morgan rescued Forest as he crashed home from long range to send the game to penalties.
Jonathan Greening hit the post with Forest's first penalty but Hamza Bencherif missed County's third spot-kick.
George Boateng and Hughes missed their penalties but Luke Chambers kept his head to put Forest ahead before Bishop's miss gave McClaren his first victory since taking charge at City Ground.
VIEWS FROM THE DRESSING ROOM
Nottingham Forest manager Steve McClaren told BBC Radio Nottingham:
"That was cup football. That was one of the best cup ties I've ever been involved in.
"It had everything, a rollercoaster. Two teams - never-say-die attitudes - just kept going and going.
"It was like a boxing match in which two opponents had had enough of dancing around and were just standing toe-to-toe, fighting in the middle of the ring and see which one fell.
"Luckily it was Notts County but credit to Martin Allen, credit to Notts County for what was a fantastic, emotional night."
Notts County boss Martin Allen told BBC Radio Nottingham:
"I am proud, it was a fantastic occasion, obviously, to come across the river to take on Forest, Steve McClaren and his squad.
"They're in a bit of a transitional stage at the moment, getting some more players in, so I thought it was a good time to come here and play them.
"I think you can see from the game that we've had a lot more chances to have won it. I think we deserved to win."
