Not sure what you mean but this is already wrong:
My FASTA sequences ( in tabular format) are not blasting
Fasta is a certain format, first you have a line starting with ">" and a description and the next line is a sequence. https://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Web&PAGE_TYPE=BlastDocs&DOC_TYPE=BlastHelp
So your file with sequences needs to be in in FASTA format not tabular. And would need to do a blastp.
