It is recommended to Get the duplicate Invoice from seller, since as per rules you're not eligible to take ITC unless you possess a valid invoice

If all the FOUR CONDITIONS as laid down U/s 16(2) of the CGST Act 2017 is satisfied, then YES you can claim ITC. Following are the Four conditions :

1). Possession of a valid Tax Invoice.
2). Received the Goods or Services.
3). Supplier must have paid the taxes.
4). Recipient must have filed the Return.

If all the above mentioned four conditions are satisfied then you can claim ITC provided that the Tax Invoice is issued in accordance with the Provision of Section 31 of the CGST Act 2017.

Agree with Shivam RC... the most important thing that the supplier upload the details in his GSTR 1 with correct details to avoid any loss of credit
