According to any of the reporting I can find, the Inflation Reduction Act: "This bill would raise $737 billion in revenue while spending $437 billion. The remaining $300 billion would go toward deficit reduction." [0]

This is pretty much the same story with every major policy proposal from the Biden administration. They all included plans to cover the expected costs.
It's pretty pointless to compare individual bills though as they are usually packaged up with the whole goals of the administration. And, as expect, Democratic administrations are far more fiscally responsible and consistently propose packages and goals that reduce the deficit.
You seem to have conflated the infrastructure bill with the inflation reduction bill.
Notably, and tellingly, any purported debt reduction from the inflation bill was made irrelevant from the $300bn of extra debt from the infra bill.
Let me know when you have an actually relevant source.
You seem laser focused on one specific bill (presumably the one bill from the Biden admin you could find with a deficit) but again, federal policy is larger than that.
