No, you cannot e-file it. E-filing is closed permanently for 2018 returns. If your mailed state return got lost in the mail, you will have to mail it again. But first you must determine whether the state received it the first time. Next time you mail any kind of tax return or document use a mailing service that will track it, such as UPS or certified mail so you will know it was received.
