TDS return - processed with defaults

For FY 2021-22, Q3, TDS return filed - form 26Q.

But mistakenly TDS was short deducted @ 1% instead of 2%.

So, for the difference amount another challan was paid along with interest but again instead of filing correction statement, it was again filed as regular statement.

Resultantly it's still displaying the return as processed with defaults and showing the outstanding demand when logged into website.

Now, what is the corrective action I should take??

What will be the consequences for that outstanding demand?

Now, can I file correction statement? Do I need to make payment again with new challan?

If I can file the correction statement, within which time I need to file it??

Confused as hell?!?! Please guide me further, friends.....
