Teemu Pukki scored twice but saw a late penalty saved as Norwich and Sheffield United had to settle for a point each at Bramall Lane.
The Canaries, beaten in their previous three matches, went in front when goalkeeper Adam Davies was slow to clear a backpass, allowing Pukki to close down the space - and the ball rebounded off him into the net.
Pukki added his second - and his seventh of the season - as a kind deflection off defender John Egan gave him enough space to angle a shot across Davies and into the far corner.
