I would wait a month unless you don’t like the shape of the shrubs. Shaping is fine now just don’t take off much since they are very young. Yellowing can be a sign of problems and sometimes it goes away. https://homeguides.sfgate.com/yellowing-boxwood-bushes-indicate-41521.html https://www.gardeningknowhow.com/ornamental/shrubs/boxwood/yellow-or-brown-boxwoods.htm
