What documents do I mail for Form 8453 with box checked for Form 8949?

Hello, in 2024 I had short-term and long-term cost basis that weren't reported to the IRS on my Form 1099-B for Charles Schwab.  Additionally, I sold a rental property and wasn't issued a 1099-S since the sale price was under $500,000.

 

TurboTax is saying I need to print Form 8453 and attach Form 8949 or an acceptable continuation sheet for Schedule D. 

 

Do I include my 1099-B statement showing the cost basis not reported to the IRS?  For the rental property, do I include the escrow settlement statement and any supporting documents/calculations that went into calculating the realized gains?

 

Many thanks!
