Always print a copy of your completed tax return for your records, and review it carefully before e-Filing.
You will need it if you are audited by the IRS, or to amend because a TurboTax update changes your return.
OR, to observe whether any penalty for under-withholding was applied.
Since you had no liability the prior year, you won't get penalized for 2019 and 1040 Line 24 should be zero.
