Thank you everyone for this great post, very detailed info for one who wants to file 3520/A.

What would be Line 2b(2) reference ID number? Is it something IRS gives/assigns to TFSA trust or Is it something bank provides?

OR Should I make any unique reference number by myself ???

Guide says "For Form 3520 purposes, a “reference ID numberâ€￾ with
respect to the foreign trust is a number established with
respect to the foreign trust by or on behalf of the U.S. person
that is engaged in a transaction with such foreign trust with
respect to which Form 3520 reporting is required. This
number is used to uniquely identify the foreign trust in order
to keep track of the trust from tax year to tax year. The
reference ID number must meet the requirements set forth"
