2019 Tax return--Health insurance gap for 2 months, which form should I fill?

Hi all,

I've got a question, so I changed job in 2018.  I have a gap of 2 months, which is allowed by the government.
What's the form I need to fill?

Thanks in advance!

No worries, guys, I figured this out.
In case, anyone has the same question:

f8965 health coverage exemptions, short gap, For this exemption, it will be “Short Coverage Gap,” which is code B under column (c) Exemption Type in Part III.
