Dear Edward K (or whoever has an idea to share):
Thank you for your info, which makes sense based on what's prescribed in Form 8453 (i.e., the last box), which is a life-saver as I'm similarly situated as the original / initial inquirer.
Now, given I have multiple accounts under one brokerage (e.g. Fidelity), (1) should I print as many Form 8453 as necessary for 1099B from each and every account, or (2) can I use one single Form 8453 and attach all the 1099Bs from the multiple Fidelity accounts altogether?
J
