Do not worry, it does not lost. Checking the status of your transfer is very simple - just visit one of the sites that track cryptocurrency transactions.
Select the site corresponding to the payment currency and indicate the address of the recipient to whom you sent the transfer. You can also specify the transaction number (TXID) that you can find in the “Transaction History” section in the payment details.

Dogecoin block explorer
Litecoin block explorer
If the amount you have sent is in the transaction list of this address, then receiving funds is only a matter of time. This usually takes from a few minutes to hours. Sometimes processing and confirmation of a transaction by the network may take longer than usual. In rare cases, up to several hours, depending on network congestion.
