GST TDS get reflected in the Cash Ledger of Receipent. So you can use your cash ledger for the payment of output tax.

Now comes to your Query :
There are 2 scheme available in Law under Composition Levy
1st scheme:
As per Section 10 (1) :
Aggregate Turnover must below 1.5 crore & can supply of Services not exceeding 10% of Turnover or 5 lac whichever is higher. So don't think that you can opt for this scheme.
2nd Scheme:
As per Section 10(2A) :
Aggregate Turnover must below 50lac & can supply goods or services or both.
So if your Turnover is well below 50 lac you can opt for this scheme.
