Thanks @jackkgan I did exactly what you listed above from step 1 to step 6 (skipping step 7 as Earned Income Credit is not my goal), but TurboTax didn't allow me to efile. The Smart Check did not report any error.
Regardless, I would suggest you to efile before 4/15 to make sure all works so you don't need to deal with any last minute stress.
Get back to my return. I initially just entered numbers (including box 12a) as they were on the IHSS W2. Smart check did not return any error, and TurboTax allowed me to efile. Guess what? IRS rejected my return with error S3-F1040-144! I created https://ttlc.intuit.com/community/taxes/discussion/2024-federal-re[product key removed]ted-with-erro... on that, and I wonder if I have to mail my return instead.
