But I just need to know if I got a lifetime visa bar for misrepresentation or fraud?
Normally if they ban you for fraud/misrepresentation, the law requires that you’re informed. In that case you would have been banned with 212(a)(6)(C)(i) Material Misrepresentation/Fraud, it would be a permanent bar which can only be removed via a waiver.
What consular officers sometimes do is they will include in your file/notes that you were less than honest. You won’t get banned outright however you’ll always get refused for subsequent nonimmigrant visas unless something miraculous happens.
The fact that they told you to apply again hints you do not have a ban.You may want to save yourself the application fee, you’re unlikely to get approved especially in these times. Overstaying has real consequences.
