AT&T/WBD spinoff -- reporting fractional shares payout in TurboTax

My wife inherited two shares of AT&T stock (T) on July 29 2004 with a cost basis of 19.25 and has held onto them since for sentimental reasons.

 

At End of Day on April 8 2022, the AT&T stock split into AT&T and Spinco stock, and each share of Spinco was converted to 0.241917 Warner Brothers Discovery (WBD). Since that came to 0.48 shares WBD, Computershare sent my wife a check for $11.53 instead of fractional shares. She received no 1099-B or other form, but just the check with a one sentence description of the transaction.

 

I used the AT&T worksheet here, that shows the post-close "aggregate basis" of the 0.48 fractional WBD shares is $9.04 and of the 2 AT&T shares is $29.46.

 

1. Does that mean the realized capital gains is $11.53 - $9.04 = $2.49?

2. How do I tell TurboTax what happened here? We don't have a 1099-B to enter field by field.

3. Do we need to use the $29.46 as the cost basis for any future transactions involving the AT&T stock?

 

Thanks!
