Direct rollover of a 401(k) from a deceased spouse account to the account of a surviving spouse

My wife and I had small identical 401(k) accounts.  She passed away in 2021, and her account was a direct rollover into my account.  Even though I entered all of the code information from the 1099 for this rollover transaction (G4), it appears as if TurboTax intends to treat this as taxable income.  I haven't moved beyond that point yet because I'm not certain if the amount of the rollover will be deducted from the total 1099 income on my return.
