Form W7

My wife entered the USA twice with a J2 visa.

First trip: October 2018 to July 2020 (with the old passport)

Second trip: September 2023 until now (with the new passport)

She is going to file a W7 form for the 2020 tax year regarding her first trip to the USA. There are a few questions:

Question 1: Which visa information should she report? The first visa or the second visa for the following section:

6c Type of U.S. visa (if any), number, and expiration date

Question 2: which visa information should be reported for the following sections?

Issued by: No.: Exp. date: / / Date of entry into the United States (MM/DD/YYYY)

Question 3: Which passport should be mailed to the IRS? The old passport or the new passport?

Question 4: If the federal tax form is mailed to the first address along with the W7 form (based on the Instructions for Form W-7), is it necessary to mail it again to the second address suggested by Turbotex?
