I didn’t rush it and did a full play through as Ravensclaw and Slytherin, plus the other two houses to get the house specific missions for the achievement.

If you go to the club page for any game you can go to the progress where hours are recorded.

On the Xbox app you can go to profile and select achievements, the more recent games will show on top. Click on one and then click stats.

Here’s all I could find

On Xbox consoles, see your time played:

Press the Xbox button  to open the guide, then select Game activity > All achievements. Select a game, then select Stats.

On the web, see your time played:

Sign in at account.xbox.com. Select your gamerpic (top-right), then select Xbox Profile > Achievements. Select a game, then select Achievements again. You’ll see your minutes played among the stats shown.

For a total there might be some site or service that helps with that but I don’t know of it.

Edit: actually Xbox is doing a year in review right now that has the total.
