I though this is Amazon Sword.
Am I right?

Looks like a Melon sword to me.

Thank you. My LFS sold this as an Amazon Sword.. got the wrong one then... I read this one need CO2 and medium light. I guess this is why the leaves are dark.

I agree, some type of melon sword. Many times all the bigger swords are called "Amazons" but they really mean echinodorus of any kind or variety. You can probably grow it but it may not be as pretty. The new leaves may be smaller & a different shape &/or color

Plan to lose the old leaves as it adjusts to your tank. Most are grown in nurseries with the leaves out of the water & the plant can use the co2 in the air. All swords like a root tab every 3 months

I did cut the leaves that were turning brown/dead. It currently has 2 new leaves from the middle.
I also put in root tabs.

In my experience, the care for the two isn't that dissimilar. Root tabs are always incredibly useful. But should be fine without supplemental CO2 as long as light isn't too high.

Yep, I've grown "swords" in low-medium light but never as pretty as emersed leaves. At least you have new growth! That's good.

Yeah I though this one was Amazon Sword... And I was wondering why the leaves are not light green. Its dark green.

They may change as they grow, new grow may be red & age into green. Leaves are apt to be smaller too, not always a bad thing, some get huge.

In general "melon" swords have rounded leaf tops; "Amazons" pointed leaf tips.
